Git - Basics - multichoice questions

Question 1

Given:

$ git init testrepo
$ cd testrepo
$ git commit -m "my first commit"

What is wrong?

You forgot to add files to the staging area before committing.
The git commit command is missing the -a flag to include all changes.
The repository isn't initialized.
The initial commit requires the --allow-empty flag because there are no changes.

Question 2

When you clone a repository, which of the following statements is true?

Some files are not tracked.
None of the files are tracked.
All files are tracked.
Only new files added after the clone are tracked.

Question 3

After running git add . (staging all files), what would be the output of git diff?

The differences between the working directory and the staging area.
The differences between the working directory and the latest commit.
The differences between the staging area and the latest commit.
No output, because there are no differences to show.

Question 4

What does the HEAD in Git represent?

The most recent commit in the repository.
The current branch name.
The commit where your working directory is currently pointing.
The first commit in the repository.

Question 5

Given:

$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   test_it

Untracked files:
  (use "git add <file>..." to include in what will be committed)

    DATA

Running git commit -a -m 'Add new benchmarks' will:

Commit the changes to both test_it and DATA.
Commit the changes to test_it only, and leave DATA untracked.
Commit the changes to DATA only, and ignore test_it.
Fail to commit because DATA is untracked.

Question 6

Adding the -a option to the git commit command makes Git:

Automatically stage all changes to tracked files and include them in the commit.
Automatically add all new, untracked files to the commit.
Automatically discard all changes in the working directory before committing.
Automatically merge changes from the remote repository before committing.

Question 7

Given:

$ git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    new file:   README

What is the status of the README?

The README file is untracked and has not been added to the staging area.
The README file is modified and needs to be committed.
The README file is new, has been added to the staging area, and is ready to be committed.
The README file has been deleted and is staged for removal.

Question 8

After modifying the config.json files in a repository, you decide to discard the changes. What command can you use?

git reset --hard config.json
git revert config.json
git checkout -- config.json
git stash
